it there any rear gears that i can get, but don't have to change to a dana44. ones that you can just swap????
I liked to know tech from a company told me that 3.73 that my car wont do over 90 with them gears because dana 36 is limted to what you can put in? yeah automaticWhat do you have? I assume it is an automatic because you mention not wanting to upgrade to a Dana 44.
The 36 will accept up to a 3.55 or so I think. 3.73 and up require a 44 case.

I understand thanks want more performance 65-80Here is the formula to figure how changing the gear ratio will effect the rpm of the engine.
Here is the formula for figuring the rpm for the different gear ratio
RPM=mph x final drive ratio x gear ratio x 336
So let’s use the final drive ratio and gear ratio for my 93 for this example
75 x .70 x 2.59 x 336 = 456876 Divided by 26 = 1752 RPM
Now all you have to do is plug in whatever ratio you want
Using a 3.73 instead of a 2.59 will have the following results at 75 MPH the RPM will be 2530 or 778 RPM more per mile.
You can simulate this by dropping the trans into a lower gear that puts the rpm in that range at 75 to see if you would like that on the road.
As others have said the MPG and the traction will be big issues but this would give a lot lower end performance without touching the engine.
If the engine has any miles on it this will increase the piston wear factor by about 7% because of the increase in what is called feet per minute.
